Abstract

The utility model discloses an apparatus for preventing common cold of children which relates to a sound signaling device used to generate the sound when the children and the infant kick the quilt and piss during sleep. The apparatus for preventing common cold of children is composed of a photosensitive diode, a transistor, a music integrated block and a buzzer. The inlaid photosensitive diode can be used to sound when the children kick the quilt during sleep. Two externally arranged small electrode plates can be used to sound when the infant pisses. The adult can deal with in time to prevent the children and the infant from catching cold. The apparatus for preventing common cold of children can also be used for other signaling purposed by often changing the receiving element. The static electric current of the complete machine is only 1 ma and the signaling sound can reach 40-60 decibel.

Description

Apparatus for preventing common cold of children

This utility model relates to sound alarm device, is suitable for carrying out sound alarm by knowing when children's's infant sleep is played by, piss.

People Chang Yin catches a cold and ill flu, particularly catches a cold and catches a cold easily especially for the more weak children's of resistance, infant.When in children's sleep, playing, the adult is in time learnt prevents to catch a cold flu by, infant piss, this for each family but a nerve-racking thing.And address this problem the purpose that this utility model just will reach.

Therefore, task of the present utility model be to provide a kind of have easy to use, element is few, make children's's preventing cold device of informing with sound alarm when being used in children's's sleep easily and playing by, infant piss.

The technical solution of this utility model sound alarm children's preventing cold device by: receiving-member, amplifier unit, sounding parts and function switch ［ K ］ are formed.Receiving-member is divided into built-in interior receiving-member and external outer reception parts, wherein: interior receiving-member is that light sensitive diode ［ D ］ constitutes, and receives parts outward and is by socket ［ CZ ］ with by tie ［ L ］ link plug ［ CT ］ together, two small electrode plate ［ GP ₁, GP ₂Constitute.Amplifier unit is made of audion ［ BG ］ and resistance ［ R ］.The sounding parts are to be made of music-integrating block ［ IC ］ Homeway.com Chinese percussion instrument ［ Y ］.Operation principle of the present utility model and working condition are: one, and be used for children's sleep and play and be apprised of use, function switch this moment ［ K ］ is allocated to the G end and links to each other with the Q end.This device is put in the quilt, when children's kick open by the time (night indoor glim lamp should be set), because light sensitive diode ［ D ］ is subjected to light, optical signal is converted into the signal of telecommunication, produces electric current, and audion ［ BG ］ obtains base current and enters saturation from cut-off state, the trigger end ［ 2 ］ of music-integrating block ［ IC ］ is high potential, under the effect of evoked potential, music integrated fast ［ IC ］ work drives news Chinese percussion instruments ［ Y ］ and sends audible signal.Its two, be used for infant piss and inform use, function switch this moment ［ K ］ is allocated to the Q end and links to each other with the N end.Plug ［ CT ］ is inserted socket ［ CZ ］, and two small electrode plate ［ GP that will link with plug ［ CT ］ ₁, GP ₂Put into bady's diaper (two small electrode plate ［ GP ₁, GP ₂Can not collide).When infant is pissed,, make two small electrode plate ［ GP because urine can be conducted electricity ₁, GP ₂Between resistance value descend, make audion ［ BG ］ obtain bigger base current and enter saturation, trigger music-integrating block ［ IC ］ work, drive news Chinese percussion instruments ［ Y ］ and send audible signal.

So far, this utility model technical solution has reached its intended purposes.Children's's preventing cold utensil of the sound alarm of making has circuit simple, reasonable in design, only with minute quantity be simple and easy to several elements can make success.Can be used for playing being apprised of and can be used for piss and inform, can also be used for other alarms by the external different receiving element of socket and use.Therefore the complete machine quiescent current is 1mA only, can use button cell, can make very little that volume does.The sound can reach 40～60 decibels during alarm.

Fig. 1 is the circuit theory diagrams of children's's preventing cold device of the present utility model, also is the embodiment circuit connecting figure.

Fig. 2 is plug ［ CT ］, tie ［ L ］ and two small electrode plate ［ GP in this utility model China and foreign countries receiving-member ₁, GP ₂The connection sketch map.

Narrate this utility model embodiment with reference to the accompanying drawings; Each element in children's's preventing cold device of the present utility model takes following manner to connect: the emitter stage of audion ［ BG ］ links to each other with the anodal three of power supply ［ Ec ］ with the power end ［ 1 ］ of integrated package ［ IC ］, the colelctor electrode of audion ［ BG ］ links to each other with trigger end ［ 2 ］ three of integrated package ［ IC ］ with an end of resistance ［ R ］, and the base stage of audion ［ BG ］ links to each other with the Q end of function switch ［ K ］.Two outfans ［ 4,5 ］ of integrated package ［ IC ］ connect news Chinese percussion instrument ［ Y ］ two ends, the earth terminal ［ 3 ］ of integrated package ［ IC ］ ground connection afterwards that links to each other with the positive pole of light sensitive diode ［ D ］ with an end of socket ［ CZ ］ with the other end of resistance ［ R ］ and link to each other with the negative pole of power supply ［ Ec ］.The other end of the N termination socket ［ CZ ］ of function switch ［ K ］, the negative terminal of the G termination light sensitive diode ［ D ］ of function switch ［ K ］.The outer connection that receives parts is: plug ［ CT ］ meets two small electrode plate ［ GP behind tie ［ L ］ ₁, GP ₂, two small electrode plate ［ GP ₁, GP ₂Can adopt a two-sided copper clad plate to make, the Copper Foil on two sides is respectively as battery lead plate ［ GP ₁And battery lead plate ［ GP ₂Use.
